Port of Numerical Python to Jython (Java Python) to support all mathematical operations (linear algebra, matrices, DSP, wavelets, FFT, arrays...) and thus compete with commercial packages such as Matlab. It can be easily embedded in Java programs.

The jTkinter module is a complete java/JNI implementation of the builtin python module _tkinter for use
with the JPython-1.1 environment. The jTkinter module allows the original lib-tk\*.py files from CPython,
